Application led, February 18, 1920. Serial No. 359,558.

To all w 7mm t 'may concern Be it known that I, RAY W. lVooD, a citizen of the United States, and a resident ot the city of lichwood, in the county of Union and State of Ohio, have invented a new and improved Tire, oiwhich the following is a. full, clear, and exact description.

This invention relates to improvements in tires, an object of the invention being to provide within the ordinary shoe an expansible element sustaining the shoe in extended formation and provide in the shoe a contractile element for clamping the shoe around the rim.

A further object is to provide a tire which dispenses with the necessity for an inner in fiated tube which causes the shoe to flatten when the tube is punctured or there is a blow-out.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings:

Figure 1 is a view in elevation of my improved devices for insertion in a shoe.

Fig. 2 is a view in cross section through a '3o shoe showing my improved device therein,

the section being on the line 2-2 of Fig. 1. Figs. 3 and 4 are fragmentary views in longitudinal section.

Fig. 5 is a fragmentary plan view of the tire clamping member.

1 represents an ordinary shoe, supported on a rim 2, the latter located around a Wheellelly 3.

Within the shoe 1 my improved devices 4 4o and 5 are located.

The device 4, constitutes an annular expansible support for the shoe and comprises a circular series of segments 6, spaced apart by means of pins 7 and bolts 8. The pins and bolts are alternately arranged and the pins 7 have rounded ends seated in curved sockets 9 in the segments 6.

The bolts 8 are headed at one end, rounded at the other end and screw-threaded at their intermediate portions. The alternate members 6 of the device 4 are provided at one end with an opening 11 in the tongue portion 14 and the adjacent tongues 14 on the adjacent members 6 are provided with curved recesses receiving the rounded ends 10 of the bolts 8. As shown clearly in Fig. 4 the bolts S are located through the openings 11 with the heads 13 conned entirely within the segments G, the rounded end 1() fitting the curved recess of the adjacent segal ment, and nuts 12 are located around the threaded portion of the bolts between the ends of the adjacent segments.V The nuts 12 may be adjusted to increase the diameter of the device 4 and hold the shoe expanded as 65 will be readily understood.

The annular device 5 constitutes a clamping means to secure the shoe around the rim, and consists of a circular series of segments 15 connected by bolts 16 which are projected 70 through perforated lugs 17 on adjacent segments 15 and have heads 18 at one end and nuts 19 at their other ends and it will be noted that by adjusting the nuts 19 the de; l vice 5 cantbe given the desired diameter. i 75 Two of the segments 15 are connected by a coupling means such as shown in F ig. 4. Hook-bolts 2O are secured in the lugs 17 and pivotally support the inner ends of links 21. The outer ends of the links 21 are pivotally 30 connected to a curved bar 22 and a bolt 23 is secured against turning to the bar 22 and extends radially of the tire through the rim 2 and through a smooth nipple 25 in the,l telly 3 and has a nut 27 on its inner end. By 85 turning the nut 27 the bar 22 can be moved radially and the links 21 will act as toggle levers tending to contract or permit the member 5 to expand.

The operation is as follows :'The expansil 90 ble device 4 is positioned in the shoe 1 and adjusted to. give the desired internal support to the shoe. The contractile member 5 is placed in the shoe in its expanded form and the shoe is located in the rim 2. In placing the shoe on the rimit is obvious that the bolt 23 is first projected through the nipple 25, the nut'27 is then screwed on to the bolt 23 and the shoe secured to the rim by operating vthe nut to contract the device 5.

It is of course to be understood that the respective segments 6 and 15 are shaped transversely and longitudinally to conform to the internal shape of the shoe, and are as light as possible, consistent with strength and durability. Vhen a part is injured or broken, it can be replaced readily, and all possibility of flat tire is entirely overcome.

Various slight changes might be made in the general form of the parts described withl] 0 out departing from my invention, and hence do not limit myself to the precise details set forth but consider myself at liberty to make such slight changes and alterations as fairly fall Within the spirit and scope of the appended claims.

I claim:

1. A tire, comprising a shoe, an expansible element in the shoe, comprising a circular series of segments, pins between certain of said segments holding them apart, bolts connecting other of said segments, and adjnsting nuts on the bolts holding the seg ments apart und permitting adjustment of the element.

2. A. tire comprising e shoe, a contractable element in the shoe comprising segments, de- Vices connecting the segments, and means for contracting said element clamping said shoe around the rim.

3. A tire, comprising a shoe, a contractile element in the inner portion of the shoe, comprising segments, devices connecting the segments, links pivotally connected to the adjacent ends of two of said segments, a bar connecting the links, a bolt secured to the bar and projected through the shoe and rim supporting the same, and a nut on the bolt adapted when turned to move the bar radielly and cause the expansion or contraction of said element.
